- Herewith the material I started to use in a reply re pseudoscorpions
- and things: it ought to be separated out. Seems to me, though, that we
- ought to be in one of the environmental conference areas.
-
- The place: Sydney, Australia, on a sandstone headland covered in
- depauperate heath (due to a lack of fire for too long, the under storey
- died out, and when then inevitable fire came, weeds were ready to move
- in. But that's another story, as they say.) It is now late spring, the
- cicadas are in full scream, and the ultraviolet is getting wuite
- dangerous in the middle of the day.
-
- I had to clean out one of the terrarium tanks today, as the frogs which
- usually live there have all got big enough to release, or they have gone
- for a holiday at the museum, where they are cleaning out the slugs in
- one of the terraria there. The springtails had taken over, and I must
- have flushed out about 3000 of them, while waiting for some paint to dry
- and some glue to set. Tomorrow, I go out to the timber yard, and on the
- way back, I'll collect some moss specimens (we seem to have about
- fifteen species around Sydney) to replant the tank, as I have some
- tadpoles starting to develop legs in one of the other tanks. At the
- moment, the fresh tank has two large millipedes (I need them for a
- photo, when I have time to walk them across some really dry sand), a
- small skink (hopefully eating the last of the springtails) and a
- click-jack beetle who has probably been gulped by the lizard by now.
- I'll gather up a few fern fronds with sporangia at the same time.
-
- I set tanks like this up with sloping soil or sand, and I always have
- free water at the bottom, so that there is a saturated level all the way
- through, and constant high humidity. Ferns will grow from spores in
- this sort of tank (although I often "hatch" the spores on mud agar
- first), and mosses, club-mosses and liverworts have a marvellous time.
- I usually just cover the tank with fly-wire, tied down tightly to
- prevent escapes or invasions by currawongs. If there are frogs in the
- tank, I make a hole in the fly-wire, invert a plastic bottle with the
- bottom cut off, fill it with leaf litter, and poke the neck of the
- bottle through the hole, so there is a constant rain of wee beasties
- into the tank below. With no frogs, the beasties tend to multiply
- furiously, and so the need for a clean-out.
-
- I've been at home building and things for the last two weeks: mainly a
- sort of conservatory for the plants and animals mainly. The feral birds
- (sparrows, Indian mynahs, pigeons, bul-buls and starlings) have been
- noisy around the house, and the currawongs have been attacking the
- crows, as have the wattle birds. One of my colleagues at work has been
- leaving out fake nests (made from tennis balls) with fake eggs, made of
- soft clay, to find out what steals most of the eggs (the eggs are
- attached to the "nest" with fishing line). The crows have made their
- marks on very many of the eggs that have been left around. Would that
- they would attack the Indian mynahs and the sparrows, not to mention the
- starlings which have moved in recently.
-
- The koels have arrived from New Guinea, and shriek out at anything after
- three in the morning, the kookaburras start in around 4, and the
- currawongs start shouting soon after. These last are very stupid birds,
- for I will swear that their call is "coq-au-vin". They get their
- (allegedly) echoic name from their call, but it is far more like
- coq-au-vin to my ears. Maybe I get hungry sooner when I am doing
- physical labour!
-
- Enough for now, though,
- peter slightly less down under
